How do you cache LLM responses safely to reduce latency and cost?
Answer
Cache when outputs are deterministic enough.
Techniques:
- Cache embeddings and retrieval results
- Cache prompt+context hashes
- Use short TTLs for dynamic data
Avoid caching sensitive content, and include model/version in cache keys to prevent mixing outputs across model changes.
